HI,
is it possible to have a listview with datapager inside an update panel and do asynchronous postback without full page rendering when i do the paging in data pager.
I tried adding both controls inside the update panel, it didnt work
Tried registering with ScriptManager1.RegisterAsyncPostBackControl(DataPager1) it didnt work too.
any other idea, both my controls are inside update panel. and uses a sqldatasource
Here is a similiar question to your problem.

I'm using bootstrap popover in a update panel in my asp page that it doesn't work. when I put it out of update panel it's OK, please help me.
There's not a lot to go on here, but when I've run into similar issues in the past it's been because the update panel does a partial postback for an update and the javascript isn't getting bound because the markup changed or was added after the page load. You will need to rebind the trigger (initialize the popover) when the AJAX panel updates using the methods described in this question.
I have a scenario... a page with multiple update panel, each update panel has some controls (with auto postback-on) and custom validator associated with this control.
The problem is... on postback of the control in an update panel, all custom validators in preceeding updatepanels in the page gets fired.
Googling the issue didnot give a clear solution.
How can i stop this from happening ? Is it a bug or am missing some thing ?
in the updatepanels set up Mode="Conditional" and then declare the triggers for each update panel. This way each update panel is selective in the triggers that will set it to update.
how about this solution using validationgroup:

I have a problem with expanding/collapsing a Treeview control in an Updatepanel which causes weird behavior and functions fine if placed outside the Updatepanel.
I have found that TreeViews is not supported in updatePanels so my question is:
What is a workaround to avoid a full postback whilst keeping expand/collapse functionality as well as TreeNode_clicks that updates another control?
Also why does it seem that some people use a TreeView inside an Updatepanel with success? Is this only an ASP2 prolbem?
It's the loading of the treeview javascript that fails under an updatepanel. I've tried putting some explanations and options below in bullet points.
The control will work in an updatepanel if it is visible straight away.
The control will not work in an updatepanel if it is made visible after a postback.
If you disable the client side javascript, the control will work in an updatepanel but will cause a postback every time a plus/minus is clicked.
Hope that helps
TreeView in .Net 2.0 doesn't need to postback on expand/collapse.
Have you tried to put an UpdatePanel around the control you wish to update with a trigger
< asp:PostBackTrigger ControlID="treeView" />
As declared by Microsoft, treeview is not compatible with UpdatePanel. So you are having all the issues. I have managed the same to a quite acceptable level in one of my project. You can refer to the posts on the same as follows: http://www.geekays.net/post/Using-TreeView-inside-AJAX-UpdatePanel.aspx and http://www.geekays.net/post/TreeView-control-postbacks-on-check-and-uncheck-of-the-nodes-Checkbox.aspx
Let me know if it helps.
I have tow diferent implementations for the same problem.
A gridview that is binded with some data and it has a select column that has a button. When the button click is fired I know in debug that the : sender.SelectedDataKey and sender.SelectedIndex have values that I use later.
But now I whant to use the ajax accordion control. I have an Accordion, and one Pane inside. Inside that pane I have a CollapsiblePanel (that uses the CollapsiblePanelExtender). And in that CollapsiblePanel I have my Gridview.
So, only when I click on the collapsiblePanel I want to get data from DB and bind it to the GridView. But it seems that using this methot the sender.SelectedDataKey and sender.SelectedIndex are Nothing (VB) when the PageIndexChanging fires!
This does not make any sense!
The GridView is the some on both implementations and EnableViewState=true
Thank you.
With the Accordion Panel being an Ajax control, it might be adding the Update Panel in there even though you did not add one to the page. Since the GridView is inside of an Ajax control, all the events that are being triggered by the GridView are going to be captured by Ajax. You might try making the GridView button clicks an Ajax callback as well.
I have run into this problem before where the controls inside of an Ajax Update Panel or an Ajax control; such as the Accordion Panel, fire the server side event handler, but because Ajax is involved, the values were stuck back on the client side.
be sure that your controls are in the same UpdatePanel, or update the various container UpdatePanels.
I have a panel on an aspx page which contains an UpdatePanel.
This panel is wrapped with both a PopUpControl Extender as well as a DragPanel Extender.
Upon initial show everything works fine, the panel pops up and closes as expected and can be dragged around as well.
There is a linkbutton within the UpdatePanel which triggers a partial postback. I originally wanted to use an imagebutton but had a lot of trouble with that so ended up using the linkbutton which works.
Once the partial postback is complete I can no longer drag the panel around.
I would love to hear suggestions on how to fix this.
Has anyone else encountered this problem?
What did you do about it?
Do you know of any other way to accomplish this combination of features without employing other third party libraries?
Take a look at when the drag panel extender and popup control extender actually extend your panel.
Chances are those extenders work on an initialization event of the page. When the update panel fires and updates your page the original DOM element that was extended was replaced by the result of the update panel. Which means that you now have a control that is no longer extended.
I don't really know of an easy solution to this problem. What will probably work is if you can hook into an event after the update panel has updated the page and extend the panel again.
